Technology is disclosed that provides security for data stored in a non-volatile memory device. The non-volatile memory device may be embedded in a host system. The host system may further have a host controller that is configured to obtain a memory access message from an initiator to access the non-volatile memory. The host controller may be further configured to provide the memory access message to the memory controller. The memory access message may contain an identifier of the initiator, which may be verified by the host controller. The memory controller may be configured to access the identifier of the initiator from the memory access message, and grant or deny non-volatile memory access to the initiator based on whether the initiator has access rights to a region of the non-volatile memory to which the initiator seeks access.
